The exposed stratigraphy on the island includes the Upper Jurassic Nanyuan Formation, the Lower Cretaceous Xiaoxi Formation, and Quaternary strata. The lithology of the Langqi pluton mainly consists of granite with MMEs (Mafic microgranular enclaves) and doleritic veins. The samples for this study were collected from the southeastern region of Langqi Island, including the host granite and MMEs. The host granites were formed in the late Early Cretaceous, and they exhibit mineralogical and chemical characteristics of I-type granite. The host granites and MMEs are significantly enriched in light rare-earth and large-ion lithophile elements, while they are depleted in heavy rare-earth and high-field-strength elements, indicating a signature of arc magma and suggesting the formation of the Langqi pluton in a subduction environment. This is consistent with the continuous subduction of the Paleo-Pacific Plate during the Middle Jurassic to Early Cretaceous.
